SLEEVED PHOTO ALBUM PAGE AND MEANS AND METHOD FOR MAKING SAME ABSTRACT OF THE DISCLOSURE The application discloses a means and method for manufacture and assembly of a known pivotally mounted sleeve-type photograph- ic print display device. The display device comprises a rela- tively rigid planar cardboard base to which there are pivotally attached to at least one surface thereof in mutually staggered relation, a plurality of individual open-ended flattened sleeves each having a paper insert of congruent dimensions. Attachment to the base is by an adhesive strip which forms a hinge. The method of manufacture and assembly includes the steps of forming a continuous web comprising a paper strip enclosed by a strip of clear synthetic resinous material forming a fold edge and a pair of oppositely disposed abutted longitudinal edges, sealing the abutted edges to form a continuous sleeve, applying a continuous strip of adhesive material to one surface laterally therefrom and expose an unadhered adhesive surface, cutting the web transversely at uniform intervals to form individual sleeve ele- ments, providing a jigging structure for receiving a predeter- mined number of individual sleeve elements in mutually spaced parallel relation with exposed portions of said adhesive strip projecting outwardly therefrom, and pressing said jigging struc- ture against a surface of a base element to adhere the project- ing portions of the adhesive strips thereto. The means for accomplishing the above steps semi-automatically includes an elongated guide element for assembling the continuous web, an ultrasonic sealing means for sealing the above mentioned abutted edges, means for laminating the adhesive strip thereto, means severing the web and feeding the severed segments thereof in timed relation with the advancement of said jigging means past a leading station. - 1 -
